Martin D. Hart, former member of the Texas state senate who started the Civil War as a Confederate captain but later switched sides, was captured by Rebel forces on January 20, 1863.
Hart made no bones about his Unionist sympathies and openly opposed secession. But, like many of his kind, he joined the Confederate army. Once in Missouri, however, he and his entire company changed uniforms and fought rearguard actions against their former comrades. Two days after his capture, Hart was court-martialed and hanged.
